Application filed December 12, 191?. Serial 3*! 0. fifiiifi aifi To all whom it map concern:

Be it known that L dosmnh AnAMs, a States, residing at Rock Island, in the county of Rock Island and State of Illinois, have invented certain which it appertainsto make and use the iii same i y p This invention relates to lugs for traction wheels and the'like-and the primary object of the invention is to provide an improved. means for attaching the lugs to the traction Wheels, so that the'same can be readily removed from or placedon the traction wheels,

A further object of the invention is to provide the improved lug with a rectangular head, which is adapted to extend through an opening of the same configuration formed in the rim of the traction wheel, and to have a locking plate for the lug, the lockingplate having an opening-therein of the same configuration as the head, and the head having a narrow rounded reduced neck portion forming shoulders on the head, so that the locking plate can be turned onthe head for engaging said shoulders to prevent the removal of the lugs from the traction wheels.

A further object of the invention is to provide a lug fastener of the above charac' ter, which includes a locking plate for engaging the lug to prevent removal thereof, said locking plate having means for engaging the rim of the traction wheels, whereby accidental movement of the locking plate is eliminated. v y

A still further object of the invention is to provide a lug fastener of the above character, which is durable and eflicient in use, one that is simpie and easy to manufacture, and one. Lt car he placed upon the market at a reasv labli. cost. "With these and other objects in view, the invention consists in the novel construction, arrangement and formation of parts, aswill he hereinafter more specifically described, claimed and illustrated in the accompanying drawing, forming a part thereof, in which: Figure 1 is a fragmentary side elevatlon of the traction wheel showing the improved lugs attached thereto, portions of the trac tion wheel and the lug attaching means being shown in section.

V Fig. 2 is a fragmentary plan view of the internal surface of a traction l rim, showing the improved lug in position and the locking means therefor;

Fig. 3 is a transverse section taken on dine 3 -3 of Fig, Fig. is a detail perspective view improved lug. l Fig. 5 is a detail perspective view of th improved locking plate, and

Fig. 6 isa perspective view of a fragment of the rim of the traction wheel. showing ithe opening for receiving the head of the L'i. ,Joui. hilt;

Referring to the drawing, in detail, where- I in similar reference numerals designate corresponding parts throughout the several views, the numeral 1 generaily indicates the improved lug, which is adapted to he attached to the rim 2 of an ordinary type of tractionwheel 3,

The improved lug 1 includes the head or ground engaging portion 4, and the reduced upwardly extending polygonal shank 5. The head. 4' has its opposite side surfaces in clined downwardly as at 6 to provide a sharp ground engaging cleat The rim 2' of the wheel 3 is provided with polygonai opening 7, of the same configuration as the a shank,- The shank 5 is reduced intermediate its ends to the central portion t. reef to provide rounded reduced neck 8, for a purpose, whieh will hereinafter more fully ap pear.

A substantially fiat rectangular locking plate 9 is provided for engaging the shank 5 and the inner surface of the rim 2 to prevent the removal of the lug i, and the plate is provided with a polygonal opening 10, which is of the same size and configuration as the shank 5. V

When the lug 1 is to be positioned on the rim. 2 of the traction wheel 3 the reduced shank 5 is positioned through the opening T and the locking plate 9 is positioned on the upper surface of the rim 2 and the shank 5 is positioned through the opening; 1Q, and the plate 9 is then turned on the reduced neck 8 until the polygonal opening 10 extend? across the opening '2', and the side walls of the opening 10 will engage under the shoul ders 11 formed on the shank 5 by cans the reduced neck portion 8.
